Scientists Discover Protein Triggering Diabetic Blindness
UCL researchers identified LRG1 protein that initiates diabetic retinopathy by constricting retinal blood vessels and reducing oxygen supply. Blocking LRG1 in mice prevented early damage, with a drug targeting it advancing to clinical trials.
Experts hail it as a potential vision-saving therapy for millions with diabetes.
Rip1 Protein: New Bacterial Defense Against Viruses
University of Toronto and Caltech teams found Rip1 protein detects viral shell proteins, forming pores to kill infected bacteria before replication. This mechanism could inspire synthetic molecules to combat antibiotic-resistant bacteria.
Research published in PNAS Nexus highlights its potential as a novel antibiotic class.
Bacteria Survive Asteroid Impact Simulations
Johns Hopkins study used a gas gun to subject Deinococcus radiodurans to 3 GPa pressures, with 60% surviving and activating DNA repair. Findings provide strongest evidence for lithopanspermia, life transfer via asteroid debris between planets.

Google Research: AI as 'Co-Scientist' Accelerates Discoveries
At Davos 2026, Google VP Yossi Matias discussed AI systems generating hypotheses, analyzing literature, and aiding research in climate and healthcare. Examples include flood prediction for billions and AI diabetic retinopathy screening 20% more accurate than prior methods.
Partnerships with Stanford show AI proposing novel hypotheses rapidly.
New Kreutz Sungrazing Comet C/2026 A1 (MAPS) Brightens
Discovered early 2026, this 2.4 km nucleus comet is the most distant Kreutz sungrazer found pre-perihelion on April 4. Models predict peak magnitude -4, but too close to Sun for safe viewing; possible bright tail in twilight.
Larger than typical family members, exciting observers despite low northern visibility odds.
